 Original plans for Northern Ireland's motorway network had the M2 route running from its diverge with the M22 near Antrim and continuing past Ballymena towards Coleraine, but on the suspension of the Northern Ireland government in 1975, the M2 link between Antrim and Ballymena remained unbuilt.The A26 was re-routed under the unused bridges of the roundabout at Junction 10 at Ballymena, leading directly onto the M2 by-pass.The road works were completed in 2010.
